In an application I\'ve built I noticed that the ImageViews are not tinted on devices running the new Android Lollipop. This is the code that used to work correctly on older ver

    As per @alanv comment, here goes the hacky fix to this bug. Basic idea is to extend ImageView and apply ColorFilter right after inflation:

    public class TintImageView extends ImageView {
    
        public TintImageView(Context context, AttributeSet attrs) {
            super(context, attrs);
    
            initView();
        }
    
        private void initView() {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                ColorStateList imageTintList = getImageTintList();
                if (imageTintList == null) {
                    return;
                }
    
                setColorFilter(imageTintList.getDefaultColor(), PorterDuff.Mode.SRC_IN);
            }
        }
    }
    

    As you might guess, this example is somewhat limited (Drawable set after inflation tint won't be updated, only default color of ColorStateList is used, and maybe something else), but if you got the idea you can fit it to your use-case.
